yes, LifeView always has a lot of OEMs. Also the first generation of the
tda8275 tuner found on some is not in production anymore and they use
the tda8275a now, maybe they change more with this replacement.

You and Werner have only one hybrid tuner at 0x61 for dvb-t and analog.
I really thought it is a clone too. Did you ever try radio?

Yes, that is the OEM subdevice :0306 Peter Missel added recently.

It has the analog tuner at 0x61 and the separate digital tuner at 0x60.
That is why one can watch DVB-t and analog TV at once from the tuners on the board.
It has also separate antenna connectors for dvb-t, analog TV and FM radio.
RF input switching happens only for analog TV versus radio with gpio21 of the PCI bridge.

There are no complications to initialize everything like on hybrid cards,
when changing the usage modes. Behaves more like two different cards.
On that one is also a different gpio remote controller, which is already supported.

Seems to be a voltage regulator, but was not seen/mentioned yet.
